Specter Finally Defects to the Democrats

Senator Arlen Specter (RINO-PA) announced today that when he runs for reelection in 2010, he'll do so as a Democrat.  The only loss to the Republican party that this represents is that if he wins reelection, it will get the Democrats one vote closer to a fillibuster-proof majority (assuming they don't lose any other seats).

Despite the verbiage of Specter's announcement (see above link), IMO the real reason is that he'd likely get spanked by challenger Pat Toomey in the Republican primary, according to this latest poll.

CNN has a good story on this here.
